Giant ATX 890

I have a small 17.5" Giant ATX 890 frame. I bought it second hand from a New Zealander.

I dont know what Axel to crown length it takes.

The Frame is black at the front and yellow rear, it has a Aluxx 95 sticker on it , and it has hydro disk pipe slots along the frame, and a raised disk mount. One that almost stands straight up. It has a Inegrated headset, and has an overall weight of 3lbs dead with nothing on it.

Can any one advise me as to what fork it takes, and what stem length works.
im looking at a pace RC31 rigid fork, but there are 80mm adjusted and 100mm versions.

Hope some one can help as i dont even know the age of it and giant didnt help much either.

I'm reasonably confident 80mm would be the go - I don't think they've made the ATX's for a few years and 100mm geometry is fairly recent for the xc hardtail market.
